Abstract

Selon l'invention, un sous-système de mémoire peut attribuer une première partie de blocs d'un dispositif de mémoire en vue du stockage de métadonnées de système de fichiers sur la base d'un système de fichiers et d'une capacité du dispositif de mémoire, écrire des données vidéo reçues en provenance d'un hôte à l'intérieur d'une seconde partie des blocs à une première densité de données, et écrire des métadonnées de système de fichiers à l'intérieur de la première partie des blocs à une seconde densité de données inférieure à la première densité de données.
